BrackishWater Extra Low Pressure Elements –
Introduction
Brackish Water Extra Low Pressure (BWXLP) Elements are advanced reverse osmosis(RO) membrane elements specifically designed to treat brackish water with
outstanding efficiency and low energy consumption. These elements operate at
significantly lower pressures than standard brackish water RO membranes while
maintaining exceptional salt rejection and high permeate flow. They are ideal
for industrial, commercial, and municipal applications where energy savings,
reliable performance, and high-quality permeate are essential.
By
combining cutting-edge membrane technology with robust construction, Brackish
Water Extra Low Pressure Elements offer a sustainable, cost-effective solution
for modern water purification needs.
What Are Brackish Water Extra
Low Pressure Elements?
Brackish Water Extra Low Pressure Elements are thin-film composite (TFC)
reverse osmosis membranes optimized to produce high-quality water from brackish
feed sources containing total dissolved solids (TDS) between 1,000 and 10,000
ppm. Unlike conventional RO membranes, BWXLP elements operate at extremely low
pressures—typically between 100 and 200 psi—without compromising
performance.
These
elements effectively remove salts, dissolved minerals, bacteria, organics, and
other contaminants from water, delivering pure, low-TDS permeate suitable for
various industrial processes and potable water applications.
The
extra low pressure design makes them a preferred choice for operators seeking
energy-efficient desalination solutions with long-term operational stability.
Key Features of Brackish Water Extra Low Pressure
Elements
- Ultra-Low Operating
Pressure:
Designed for superior performance at feed pressures as low as 100 psi, significantly reducing energy usage and operational costs. - High Salt Rejection:
Provides up to 99.5% salt rejection, ensuring consistent production of clean, high-purity water even under challenging feed conditions. - High Permeate Flow:
Delivers excellent permeate output with minimal energy input, increasing overall water recovery and productivity. - Durable Membrane Material:
Constructed using premium polyamide thin-film composite (TFC) materials for excellent chemig service life. - Fouling and Scaling
Resistance:
Engineered with a smooth membrane surface that minimizes scaling and fouling, reducing cleaning frequency and extending operational lifespan. - Compatibility:
Fits standard RO housings and pressure vessels, making it easy to integrate into existing systems or replace older membranes.
Performance
Benefits
- Energy Efficiency:
BWXLP elements consume up to 40% less energy than standard brackish water membranes due to their ultra-low-pressure design. - Cost Savings:
